To whom it may concern,
My name is Zhang San ( Passport No: G12345678 ), I am currently a full-time registered post-graduate student studying Biology at OxfordUniversity.
I have lived in Britainfor more than 2 years, and I have not seen my girl friend Li Si ( Passport No: G16054321 ) for more than one year. Therefore, I miss her more than I can say, and she misses me in the same way. That is why I am writing this letter to you to invite her to Britainso that we could both enjoy a marvelous time together.
I wish to invite her to visit and stay with me for 17 days or so, that is from March 20th to April 5th.
Besides, I live in a house with 45 square meters in area, which is more than sufficient for us to live in.
I hope she can come to join me as soon as possible.
Thank you in advance for your consideration of my request.
Best regards
